Fox Is ‘Cautiously Optimistic’ Supreme Court Will Stop Aereo

21st Century Fox Chief Operating Officer Chase Carey is “cautiously optimistic” that the Supreme Court will stop Aereo from streaming its broadcasts.

Television companies have tangled with the start-up because they believe that it undermines their business model. Aereo captures broadcasters’ signals and retransmits programming to its subscribers through its constellation of tiny antennas, but Carey argued that its technology violates copyright protection.

“Hopefully we get those rights re-affirmed through this process,” Carey told analysts during a quarterly earnings call Thursday.

Aereo, which is backed by media mogul Barry Diller, has launched in major cities such as New York, Boston and Denver despite being plagued by legal challenges. It has countered that the airwaves are publicly owned and it has a right to air broadcast television.

For television companies such as Fox to succeed they need revenue streams, Carey argued. One comes from advertising. The other from fees Fox charges cable, satellite and telco providers to rebroadcast their channels.
